SEPTEMBER 25, 2026 A Private Room With a Public Door Someone sent me a write-up I didn't understand at first, claiming Zcash-style privacy now works on Bitcoin itself — no soft fork, no new coin — and a real private transfer confirmed on mainnet this morning to prove it. Both halves are true. Here is how it works in plain English, what the demo actually proved, the flaws its own builders list first, whether swapping the one-key vault for a decentralized escrow would fix it, and why, if I had to make Bitcoin private for a normal person tomorrow, I would still start with Lightning. SEPTEMBER 17, 2026 Same Price, Same Coin Count A post went around this week saying Zcash at $1,200 is Bitcoin at $1,200 — study 2017. The arithmetic behind it is genuinely correct, which is the most interesting thing about it and the reason it's worth taking apart. Here is what the post is actually claiming, why the supply math works, why the conclusion doesn't follow, why my broker won't list the coin but will list the ETF, and what kind of future I think a "Bitcoin plus privacy" actually has. Shorter than the pitch: real, bounded, and not the apex of anything.
